An Investigation Of Alkaline Earth And Rare Earth Elements In Human Bone Following Long-Term Parenteral Nutrition, Aubrey L. Galusha
An Investigation Of Alkaline Earth And Rare Earth Elements In Human Bone Following Long-Term Parenteral Nutrition, Aubrey L. Galusha
Legacy Theses & Dissertations (2009 - 2024)
This investigation focused on a unique collection of archived human bones obtained post-mortem from 7 patients, who had received long-term parenteral nutrition (PN) for up to 21 years. Parenterals are administered intravenously as a nutritional supplement, and may be contaminated with metals, which are completely absorbed into the blood compartment. Some metal contaminants may be deposited in the body’s reservoir for inorganic elements – bone.
Structure And Stability Of Amyloid Fibrils Studied By Advanced Vibrational Spectroscopy, Marudachalam Shanmugasundaram
Structure And Stability Of Amyloid Fibrils Studied By Advanced Vibrational Spectroscopy, Marudachalam Shanmugasundaram
Legacy Theses & Dissertations (2009 - 2024)
Protein misfolding often leads to the formation of refractory protein aggregates like amyloid fibrils. These fibrils possess a highly ordered structure and are implicated in over 25 severe diseases including Alzheimer’s, Parkinson’s and prion diseases. This work was focused on understanding the morphology and conformation of amyloid fibrils and their stability after formation. The deconstruction of fibrils as well as other aggregates like inclusion bodies under mild conditions was also investigated using Archaeal chaperones.

Novel Nmr Based Technologies To Study Macromolecular Structures, Subhabrata Majumder
Legacy Theses & Dissertations (2009 - 2024)
Nuclear Magnetic Resonance Spectroscopy (NMR) is one of the principle tools in structural biology to probe macromolecular structures and interactions. The atomic resolution afforded by this technique has been widely used to probe protein-protein, and protein-ligand interactions in-vitro. However, the natural milieu of the proteins is the living cell and the cellular cytoplasm is extremely heterogeneous. The NMR studies of folded protein in-cell, till now, have been limited by non-specific interactions of the cytosol. This thesis outlays a general methodology to study protein structure/interactions inside the living cells using NMR. In a closely related objective, it also describes the use …
Characterization Of Metallic And Semimetallic Oxide Nanoparticles In Industrial Wastewater And Associated Toxicity, Gary Roth
Legacy Theses & Dissertations (2009 - 2024)
Engineered nanomaterials (ENMs) play an increasing role in manufacturing and consumer products. Currently, there is no standard approach to studying ENM toxicity, and a growing body of literature suggests that ENMs may have toxicity differing from similar compounds in bulk or dissolved form. I examined ENMs used in the semiconductor manufacturing process called chemical-mechanical planarization (CMP) for their properties, removal in the wastewater treatment system (WWT), in-vitro toxicity, and location post-inhalation in-vivo. It was found that ENMs in CMP slurries have morphology determined by their elemental composition, but assessment of size and concentration can differ substantially between accepted techniques. Particles …
